Do humans help or harm your forests?

Humans are a very weird species. They harm the environment and now they're asking "are we harming the environment?" Now, don't lie, i know you're a human, so....

Yes, humans DO harm the environment.They harm it in ... millions of ways!!! humans cut down forests, make pollution, and do a bunch of other crap to the environment that i can't list or wiki answers will probably ban me.

So, to make word short, humans hurt the environment more than Adolf Hitler killing Jews-_-
